At first: You get what you pay for, but this is 100% Value for money. Evan's place isn't close to Hotelstandards but it has everything you need and you'll probably only go here to sleep.
We booked on very short notice as our first booking was bad. Evan was very helpful and had us check in within a couple hours. The room looked a bit used over the years but it was clean with fresh sheets and towels and everything in place. It was at the end of a dead en street so it was very quiet outside which we enjoyed.
It's very easy to find great food and bars in walking distance to Evans place.
We were very happy with everything and will check Evans places at first when we come back to Bangkok.
